HB Home Roasting Competition Results - Brewed Coffee

Postby another_jim on Tue Feb 23, 2010 9:26 pm

The first round of the brewing competition is done; and the results are posted in the announcement.

Congratulations Ed (Farmroast), you had the top score.

The standard was very high (I was scoring ultra-tough, so it doesn't show in the numbers), and except for two or three roasts with minor technical problems, all the roasts were very tasty. The main factor in higher or lower scores was how "loud" the coffees were. In a cupping competition, the laid back coffees that might win if the coffees were brewed and drunk normally tend to get drowned out, since the tasters use a spoon and take small sips. Bottom line, if you roast for a brewing competition, it pays to go loud. The winning roasts had bold flavors and a good acidic pop.

I'll have the detailed scores and descriptions written up by the weekend.

Kudos to all the entrants. It sounds like a great competition. Looking forward to Jim's notes. This has gotten me thinking about home roasting again.

Cheers

What was fun in this brewing round is that there were four kinds of roast, and the top four finishers were the best in each category. To my taste, they put a little daylight between themselves and the runners up in each type of roast.

The first category was a light roast combo of the Maravilla filled out with the Haile Selassie; there were three entries using this idea. This combo has the Central American snappy acidity combined with a sweet finish, while the Sidamo adds a twist of floral aromas. I thought Ed's roast was the best example. On average, the entries in this category scored highest

The second category was a straight roast of the Sidamo (Yrg DP or Haile). Here you are looking for a fruit and flower bomb. Henry's roast was the best at maxing out on the aromas while avoiding the astringent, tannic finishes that can plague Yrgs and Sidamos.

The third category was a wide spectrum blend, adding a bit of the Sumatra and Brazil to the Hue-hue and Sidamo. My attempt was in this class, but it wasn't the best. Casey Blanche's roast had more pop in the flavor and acidity than mine, along with the same wide range of taste and plush creamy body. There were two more in this group that were good, but too laid back for cupping. The group as whole would have done better being slowly savored rather than tested with soup spoons.

The fourth category were darker roasts. Some people look down on these; but a dark roast is by far the most difficult thing to do well -- go too fast, and the excess heat will char the beans, go too slow and the taste is flat and astringent. David's roast was extraordinary, with lots of the caramel/molasses sweetness and complexity that makes a good dark roast so seductive. In this type of scoring, a dark roast will always drop a few points on acidity compared to lighter roasts, so the fourth place finish is, if anything, an underestimation.

I'm not surprised, farmroast. The Mamuto that you roasted and I tasted a few years ago was stunning.

Congratulations, farmroast! I still have a pound of the Maravilla, so I'll have to try blending it with some of my 2nd shipment of Haile Selassie to see if I can make something similar to what you submitted. This is so much fun!

But wow, I did much better than I expected to. It feels really good to receive this kind of feedback for the first time, since I really had no measure of how well I was doing aside from my own taste buds. I'm also glad to see that I still have plenty of room to improve. Thanks again, Jim. I can't wait to see what the others think.

Jim
Thanks for getting the results up so quickly, it's nice to get quick feedback on my efforts, I was expecting a longer wait.
If its not too much trouble, it would be nice if you could include people's handles by their names, I know some of the people, but most of them I know by their handles used here.

Everybody else,
I think I participated in this for the same reason many others did, to get a benchmark of where I'm at. I've already learned, and I think improved in some areas, just by participating in this event.
Now that we now where we stand, I would really appreciate it if we could share our "recipes". I think we could learn from each other's successes, and from our problems.

I'm all for that. I'll post the description I sent to Jim along with my sample. I'd like to hear from Henry to see what he did that might have made his roast a bit tastier than mine. Sorry I didn't record more detailed information, but I didn't really expect to submit Haile Selassie as my entry until I actually tried it the morning after I roasted.

Ethiopia DP Haile Selassie Sidamo, SO
Home-Roasting Competition - Brewing Entry

Roasted on 02/13/2010. Full City (+, maybe?). 1st crack at 9 minutes, continuing to 12 minutes and then stopped. Both 1 lb. batches I roasted had no clear gap between 1st and 2nd crack. I assume I went just barely into the second crack with this batch, but I'm not sure.

Equipment: Heat Gun/Bread Machine, no thermometer. Heat was left on high (1100F) for the duration. Ambient temp outside was in the mid 30s. The only profiling attempts involved opening and closing the lid of the bread machine for insulation against heat loss. The first and last 3 minutes had the lid open, while the middle chunk had it closed. Heat gun was handled manually and rotated against the direction of bean agitation for the duration of the roast.

So yeah, pretty sloppy. The only timer I used was the one on the bread machine that only counts minutes. I was more diligent about recording time with the previous attempts I ended up not submitting.

Jim,

thanks for the review and all of the hard work that you and all else involved put out. I am impressed that this roast of the Yirg DP turned out as well as you did. I thought it got a little too far along and started into a quickening second crack, as I was trying to go just into second.

I have lately been trying two things with my roasts: going with a 5-6 minute drying stage that stays below 325 F, and keeping the beginning of FC to end of roast 3.5-4 minutes. Most of my roasts go 14-17 minutes using the RK Drum.

I love the good dry process Ethiopian coffees and this "generic" Yirg from SM's, all twenty pounds, has been great so far.

It feels good being in such good company as Ed, Henry and the rest, AND to have kudos from you.

Thanks David "Draino" Rainiero
